VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 654,289, dated ruiy 24,1900.

Application filed November 6, 1897. Serial No. 657,618. (No model.) l

To all whom it may concern:

Be it known that I, ROBERT SEEGER, of the city of St. Paul, county ofRamsey, State of Minnesota, have invented certain new and usefulImprovements in Vapor-Burners, of which the following is aspecification.

My invention relates to vapor-burners; and one object of my invention isto provide a Vapor-burner which will maintain an even steady flame atall times and in all kinds of weather.

A further object of the invention is to provide a vapor-burner whichwill contain a minimum amount of metal, so that the burner may be easilyheated and kept at the required high temperature which .is necessary torapidly vaporize the oil fed thereto.

A further object of the invention is to provide a burner which may beeasily and quickly cleaned; and a further object is to utilize the heatof the illuminating-name as a means to vaporize the oil.

My invention consists generally of a vaporburner of the constructionandcombination of parts hereinafter described, and particularly pointedout in the claims.

The invention will be more readily understood by reference totheaccompanying drawings, forming part of this specification, 'and in whichA Figure l is a side View of aburner embodying myinvention. Fig. 2isafront View thereof. Fig. 3 is a plan view of the same. Fig. 4 is a sideview of the burner with the lower portion thereof in section, showingthe interior construction of the burner. Fig. 5 is a vertical section ofthe burner, showing va slightly-modified construction. Fig. 6 is a planView similar to Fig. 3, showing the tip in a different position.

' As shown in the drawings, the burner comprises the straight verticaltube 2, adapted to receive the removable tip 3 in its upper end. Thistip sets into a socket 4, which is of a size to leave an annular spacearound vthe tip. The tip is provided with a jet-slot 5, and also has twosmall holes 6, which holes are beneath the top 7 of the tube-socket 4,so that they deliver the gas into the annular space around the lowerpart of the tip. In the lower part of the burner-tube are air-openings8, preferably transverse saw-cuts. In the bottom of the tube is apartition 9, the top of which is finished to a cone shape by a toolinserted through the upper end of the tube before the tip is placedtherein. Beneath the partition 9 is a chamber I0, fromwhich vapor isforced into the bottom of the tube through a small central jet-hole IIinthe partition 9. 12 is a vertical web projecting from the side of the6o tube and having an integral stud 13 on its rear edge to receive andhold the shield 14, which is secured thereon by a nut I5. I6 is aretort-chamber or barrel formed integrally with the burner-tube and theweb 12 and hav- 65 ing an open top. The top of the chamber is closed bya dome-cap 17, Vwhich is screwed onto the top of the retort-chamber andcompletes the same. 1S is a tube which projects upward from the bottomof the retort-cham- 7o ber through the tube and downward through theduct 19, which is made in the web. As shown in Fig. 1, the web ispreferably enlarged to allow the boring of the duct 19,Which duct, itwill be noticed, is concentric with the tube 18 and with theretort-chamber. All of such parts are arranged at an acute angle withrespect to thelvertical Aburner-tube 2. A horizontal hole 20 is drilledin the bottom of the burner and communicates with the duct 8o 19,whereby said duct 19 and the retort are connected with the chamber I0 inthe lower part of the burner-tube.

The gasolene is led into the retort-chamber in any suitable manner. Insome burners I make the inlet-nipple, to which the oil-pipe isconnected, at the lower part of the burner, as shown in Figs. 1, 4, and5, while in others I prefer to place the inlet atv the top of the burnerand on the back of the retort, as shown 9o by dotted lines in Fig. I.The lower inlet (shown in full lines) is connected with the retort bythe vertical duct 21, made by drilling downward in the web from theretort-chamber 16 before the cap or dome 17 is fitted 95 thereto.

To facilitate the cleaning of the jet-hole 1l in the lower part of theburner-tube, the lower end of the chamber lO is closed by aneasilyremovable cap or cup 22. The cup and the roo lower end 23 of theburner-tube are provided with conical surfaces, so that the cup iits`with the other parts of the burner. shield is removable in order thatthe jet-holes `3l may be drilled and in order that the same neatly uponthe end 23, making a gas-tight joint therewith. The cup is held in placeand is snugly drawn upon the end 23 by means of an arm 24, provided uponthe cup and adapted to engage a lug upon the front or side of theburner. In Figs. l, 2, and 4 I have shown an integral lug 25 upon thelower end of the burner-tube, said lug having an inclined upper surface26, adapted to be engaged by the arm 24 upon the cup or cap 22, so thatwhen the cap is turned the same will be forced upward upon the conicalend 23 of the tube or, vice versa, will be released from the lug, sothat the cap may be taken off. The cap is provided with wings 27, to begrasped in turning the cap. In place of the integral lug 25 I may usethe pin or screw 28, (see Fig. 5,) said screw filling the hole made inthe tube when drilling the hole 20, which latter communicates with theduct I9. In this case the arm 24 will be provided with an-inclined orwedge surface to hind upon the top of the pin or screw 28. To clean outthe lower part of 'the vapor-duct leading from the retort, as shown inFig. 5, the pin 28 is first removed and a. wire or suitable tool is theninserted into the ducts 2O and 19. A somewhat simpler construction ofthe ducts and one which permits the use of the integral lug 25 is shownin Fig. 4, where the lower branch 20' of the duct 19 is made by drillinga hole concentric with the inlet-nipple 21'. The flow of oil from thenipple direct to the chamber l0 is cut off by a plug orv screw 29, thatis driven into the outer end of the transverse duct 20.

This plug is preferably made to be easily removed, so that wire may beinserted to clean out any carbon or other substance accumulating in theducts.

`jet-holes 3l. from these holes, and being ignited will `projected bythe right-angled shield 14 and by the wings 32, projecting from thesides of the burner-tube. Furthermore, to prevent an upward draft of airwithin the shield I preferably provide a horizontal floor 33, whichcloses the bottom of the shield and is integral The `may be easilycleaned at any time. As above stated, the tip 3 is removable, so thatits slot `and flame 'may be adjusted at any desired angle. p

It is well known that in cold weather most burners in warm weather.

The bottom 30 of the ref tort-chamber projects upon opposite sides of 1the integral web 12 and is inclined with respect to the burner-tube, andin the tube and upon opposite sides of the web are the small l Smalljets of gas willbe forced the fact that a certain provision' is made forheating the burner and is not changed at any time. In the present burnerI may regulate the heating of the retort by adjusting the tip so thatthe dame will more or less closely approach the upper part of the retortwhich projects above the tip, or, if necessary, the fiame may be made toimpinge directly upon the cap of the retort. This feature I believe tobe one of the most important features of my invention. One of theessential features and advantages of the burner herein described is thellightness and compactness thereof, the same containing little metal tobe heated and having its parts so closely arranged that they are easilykept hot, comparatively little surface being exposed at any considerabledistance from the heating-jets and illuminating-flame. A furtheradvantage lies in the straight ducts of the device and in the few anglestherein, all parts being easily accessible. The small jets from theholes 6 are directed upward from the annular space and tend to greatlystrengthen the flame, the same being -less alected by a wind or draft.These holes are opposite one another at right angles to the slot in thetip.

I am aware that removable tips have been used upon a number ofvapor-burners and that tips of exactly theconstruction hereinillust-rated have been so employed, but I believe that the employment ofa tip in close proximity to the retort and so arranged that theilluminating-flame will aid in heating the retort is entirely new inthis art. l

A further advantage of my invention lies in the easily-re movable capfor the lower end of the burner-tube, the same being small and light, sothat little metal is added to the burner and whereby the vapor-jet ismade easy to clean.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl.
